I'm not so sure that the way the particular interface is placed into the
OSPF process is the reason for the host routes appearing. I can't place my
finger on it at this moment. My quick search of the RFC did not yield what I
thought I remembered. But I believe that the result Mr. Sanjay is seeing has
to do with the way OSPF treats OSPF point-to-multipoint network types on a
frame relay subinterface.
Not quite sure.

Try changing the wild card mask for area 0 to 0.0.0.7.
